# Change Log: Sell Form Update & POS Implementation
Date: 2026-02-02

## 1. Initial Phase: Sell Form Removal
- **Request**: Remove all existing Sell form-related components.
- **Actions**:
    - Deleted `resources/views/tenant/sell/index.blade.php`.
    - Deleted `app/Http/Controllers/Tenant/SellController.php`.
    - Removed Sell routes from `routes/web.php`.
    - Removed "Sell" sidebar link from `resources/views/layouts/tenant.blade.php`.

## 2. Second Phase: New Desktop POS-Style Sell Form Creation
- **Request**: Create a fast-loading, desktop POS application-style Sell form.
- **Features Implemented**:
    - No image loading for faster product list performance.
    - Cart management: Quantity update, item-wise discount, item removal.
    - Unit conversion: Ability to change units and update price automatically.
    - POS Hold/Resume: Functionality to save current cart state and resume later.
    - Keyboard Shortcuts:
        - `F2`: Submit Sale
        - `F4`: Hold Sale
        - `F7`: Focus Customer Search
        - `F8`: Focus Product Search
        - `Esc`: Close Modals
    - Sidebar link restored for easy access.

## 3. Bug Fixes & Improvements
- **SQL Error Resolution**: Fixed "Unknown column 'operator'" error in `SellController.php` by updating the units query to use `conversion_factor`.
- **Unit Conversion Logic**: Implemented Alpine.js logic to multiply base price by `conversion_factor` when a unit is changed.
- **Database Schema Alignment**: Removed `unit_id` from the `sale_items` creation query in `SellController.php` to match the actual table structure.

## 4. Multi-Unit Management & Stock Logic Update
- **Request**: Implement complex unit conversion (e.g., 1 Case = 24 Pcs) and handle stock in Base Unit.
- **Features Implemented**:
    - **Product-Specific Units**: Instead of global units, the Sell form now loads units specifically defined for each product (Base, Purchase, Selling units).
    - **Unit-Specific Pricing**: Price is now fetched from the `variant_prices` table based on the selected unit in the cart.
    - **Automatic Price Update**: When changing units in the cart (e.g., Pcs to Case), the price updates instantly according to the pre-defined price for that unit.
    - **Stock Decryption in Base Unit**: When a sale is made, the system automatically converts the quantity to the Base Unit using the `conversion_factor` before decrementing stock. (Example: Selling 1 Case of 24 Pcs will decrement 24 from stock).
    - **Default Sale Unit**: The cart automatically loads the unit marked as `is_sale` for each product.

## 5. Product Variant Selection Support
- **Request**: Support products with multiple variants (e.g., Pepsi in Plastic Bottle, Can, Glass Bottle) and different sizes/prices.
- **Features Implemented**:
    - **Variant Selection Modal**: If a product has multiple variants, clicking it will now open a modal showing all available variants.
    - **Variant-Specific Information**: Each variant shows its own SKU, Name, and Price.
    - **Contextual Cart Addition**: When a variant is selected, it is added to the cart with a descriptive name (e.g., "Pepsi (Can - 250ml)").
    - **Automatic Price Loading**: The system automatically loads the correct price for the selected variant based on the default selling unit.
    - **Unique Cart Identification**: Variants are tracked separately in the cart, allowing multiple types of the same base product to be sold simultaneously.

## 6. Product Creation & Variant Logic Fix
- **Request**: Review and fix logic for product creation via `tenant/products/create` and ensure variant/stock table structures are correct.
- **Improvements Implemented**:
    - **Variant Name Fix**: Fixed `ProductController@store` to correctly save variant names from the form instead of always using the base product name.
    - **Simple Product Price Consistency**: Updated simple product creation to also generate a `variant_prices` record for the base unit. This ensures that simple products work seamlessly with the new Sell form which expects unit-based pricing.
    - **Date Fields Support**: Added `manufacture_date` and `expiry_date` saving in `ProductController`.
    - **Frontend-Backend Sync**: Updated `create.blade.php` to send variant names as hidden inputs, matching the controller's expectations.
    - **Boolean Fix**: Improved `has_variants` boolean handling in the controller to support various form input types.

## 7. Product Creation Workflow & Notifications
- **Request**: Add success notifications, redirect to product list after save, and add a "Save and Add Another" button.
- **Features Implemented**:
    - **Global Notification System**: Added a centralized notification area in the [tenant.blade.php](file:///d:/laragon/www/Laravel_gorsary/resources/views/layouts/tenant.blade.php) layout to display success and error flash messages across the entire tenant application.
    - **Save and Redirect**: Default "Create Product" button now redirects to the product list page with a success message.
    - **Save & Add Another**: Added a new "Save & Add Another" button in the [create.blade.php](file:///d:/laragon/www/Laravel_gorsary/resources/views/tenant/products/create.blade.php) form. This button saves the product and redirects the user back to the creation form to add another product immediately.
    - **Controller Logic Update**: Modified `ProductController@store` to detect which button was clicked and handle the redirection accordingly.

## 8. Product Edit Form & Variant Sync Update
- **Request**: Fix non-functional product edit page, enable new variant addition, update stock/Base Unit price, and make form fully functional.
- **Features Implemented**:
    - **Robust Variant Sync**: Updated `ProductController@update` to preserve existing variant IDs during editing. This prevents breaking historical data (like sales) linked to specific variant IDs.
    - **Intelligent Variant Regeneration**: Modified the "Regenerate Variants" logic in `edit.blade.php` to match existing variants by their attribute combinations. This preserves their IDs, SKUs, pricing, and stock even after regeneration.
    - **New Variant Addition**: Users can now add new attributes or values and regenerate variants; the system will intelligently keep existing ones and add new combinations.
    - **Price & Cost Sync**: Improved the price update logic to use `updateOrCreate`, ensuring that pricing for different units is correctly synchronized without duplicate records.
    - **Base Unit Support**: Fixed the logic to allow updating the Base Unit price and cost directly from the edit form.
    - **Stock Management**: Ensured that stock values for each variant are preserved and correctly updated during the edit process.
    - **Manual Variant Addition**: Added a "+ Add Single Variant" button that allows users to manually add a new variant row without needing to define attributes first.
    - **Editable Variant Names**: Changed variant names from static text to editable input fields, allowing users to customize variant names (e.g., "Pepsi - 500ml Bottle" instead of just "Pepsi / 500ml").
    - **Improved Checkbox Interaction**: The "This product has multiple options" checkbox now correctly toggles the visibility of the variant table even if the product was originally simple.
    - **Custom Name Preservation**: When regenerating the variant matrix, the system now preserves any custom names the user has entered for matching variants.
    - **SKU Update Fix**: Fixed a bug in the controller where variant SKUs were not being updated correctly during the product edit process.

## 9. Product List Pagination, Date Defaults & Filtering
- **Request**: Add pagination to the product list page, set default values for manufacture/expiry dates in the creation form, and add filters to the product index page.
- **Features Implemented**:
    - **Pagination**: Added standard Laravel pagination to the product index page. Each page now displays 10 products, improving loading performance for stores with large inventories.
    - **Date Defaults**:
        - **Manufacture Date**: Now defaults to the current date when opening the "Create Product" form.
        - **Expiry Date**: Now defaults to exactly 6 months from the current date, streamlining the data entry process for perishable items.
    - **Advanced Filtering**: Added a filter section to the product index page allowing users to filter by:
        - **Search**: Search by product name or SKU.
        - **Category**: Filter products by their assigned category.
        - **Brand**: Filter products by their assigned brand.
    - **Query Persistence**: Implemented `withQueryString()` to ensure that active filters are maintained when navigating between pagination pages.

## 10. SaaS Admin Tenant Category Management

    - **Tenant Categories Infrastructure**:
